WATER-Fl LTER.

SPECIFICATION formingpart of Letters Patent No. 268,776, dated December 12, 1882.

` Application filed August 24.1882. (No model.)

To all whom it may concern:

Be it known thatl I, JOHN W. BAILEY, ot' Boston, in the county ot' Suolk, State of Massachusetts, have invented a'certain new .5 and useful Improvement in Water-Filters, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said in' vention appertains to make and use the same, reference being'had to the accompanying drawing, forming a part of this specification, in whichl a vertical longitudinal section ofthe filter is shown.`

My invention relates to that class of wateru filters in which the water has a reverso dow,

or is filtered and purified by passing upward through the filtering material; and it consists in a novel construction and arrangement of the parts, as hereinafter more fully set forth zo and claimed, by which a' more effective and desirable article ot' this character is produced than is'now in .ordinary use.

The nature and operation of the improvement will be'readily understood by all con- 2:5,` versant with such matters from the following explanation, its extreme simplicity7 rendering an elaborate description unnecessary.

In the drawing, A represents the body or case ot' the filter; B, the cover; CD, the tube; E,`the duct, and G H I J the respective compartments for un liltered water, partially-{iltered water, the filtering material, and the pure or liltered water. 4

The body and other parts of the lter are preferably com posed entirely ot earthen or pottery ware, although they maybe of other materials, it' desired. Y

Projecting from the inner wall of` the bdy -A there are a series of lianges or brackets, a d,- and resting on the brackets a there is a perforated disk or foraminous diaphragm, K`, a

tight or unperforated disk, L, being disposed on the upper brackets, d, which forms a bot! tom to the compartment or tank G. A vertical tube or duct, E, connects the disks LK at their centers, said duct passing through the center of a perforated disk, M, which rests on ber or compartment I.

the top of the filtering material N in thecham- The lltering material may consist of ,animal charcoal, sand, `85o., or 5o any ofthe well-knowningredients orsubstances usually employed for such purposes. The duct E is provided at its npperend with the sponge S, and is cemented to or connected by watertightjoints with the disks L M K, these disks heilig also cemented to or connected by watertightjoints tothe interior wall of the body A.

In the use of my improvement theunliltered water is placed in the tank or compartment G,

whence it passes through the sponge S and 6o' duct E into the compartment H, from which it is forced upward through the disk K, tilt-er- `ing material N, and disk M into the compartment or tank J, from which it may be drawn through the faucet Q.

Theobject of the tube C is to clear the holes or perforationsin the disk K, which may be accomplished, in case said holes become clogged 'or lled up, by blowing or forcingl a current of air 'through said tube into the compartment H. 7o In like manner the disk M may also be cleared by means of the tube D, the outer ends ofthe tubes being closed byany convenientv means when not in use.

lf desired, a filter constructed in this "manner may be connected directly with the waterpipes or -aqueduct-pipes by means of proper fittings attached t-o the cover B or to the duct E, in which case the sponge may be used or omitted, as desired.

Having thus explained my invention, what I claim is l. The improved water-filter described, the same consisting of the body A, `disks L M K, duct E, and tubes .O D,constructed, combined, and arranged to operate substantially as specilied. 2. The tubes() D, formed in the bodyof the filter, substantially as set forth.
